Default Delta contractor blade hits insert

For the first time since I bought the Delta Contractors saw a year ago
I am trying to cut a 45 degree mitre in the ends of the jewelry box
sides. However when I tilt the blade to 45 degrees, the blade hits on
the insert. I noticed that when the blade is at 90 degrees the blade
is not centered in the slot in the insert, but I don't see where there
is anything I can do to move it over to the left a little bit. At 45
the blade doesn't hit by much but definitely hits. Don't see anything
in the manual about an auxiliary insert for cutting 45s so I what's
the problem?

The trunnion needs to be moved over so that the blade will clear the insert.
OR you can use a file and widen the slot so that the blade does not hit. If
your saw is doing a great job at providing smooth cuts when ripping, I would
make the slot wider. If the results of your cuts could use some improvement
I would move the trunnion and realign the blade parallel with the miter
slot. The later being the correct way to fix the problem.

Contractors saws have the trunion attached to the underside of the table,
usually 4 bolts. Loosen the 4 bolts and shift the trunion in the
appropriate direction, then make sure the blade is parallel to the miter
slots. In some cases, the bolt holes don't have enough slop to get it
centered. In that case, call Delta if it's new, or get out the file if it's
not.

Ross & Leon make good points.

I'd do the trimming on a home built insert, or a cheap, replacement insert
from a dealer, rather than the original, should you choose that route.

In fact, a zero-clearance, or near-zero clearance insert is often a pretty
good addition, if you provide a splitter option.

Your trunions may have enough room to allow you to center the blade or
at least move away from the insert enough that it doesn't contact. If
everything else is spot on, parallel to the miter gauge slots and so
forth, I'd just make a custom, zero clearance insert out of hardwood. I
haven't had the stock insert in my contractor's saw in years. I kid
myself that an insert for the dado head that has a slot cut by the dado
I'm using gives less fuzz/tearout on the underside of the work. Does
seem that way, though.

This happened to me out of the box with mine. I got lucky and could move
the bolts as described in another post here. In fact, I couldn't tilt my
blade to 45 until I made this adjustment or the insert would have gone
flying at my face. Not good...

I had the identical problem with my five year old Delta CS. Solved it
by using the Delta insert made for dado blades. Needed one of these
anyway so it was not a big deal.

I don't know how you would make a zero-clearance insert for 45 degrees.
The problem I see is that the usual process for making the insert calls
for raising the spinning blade up through the insert while it is held
down by the fence. If you try this with the blade set at an angle two
bad things are going to happen. The first is obvious and that is the
entry cut into in the insert will not be zero clearance because raising
the blade vertically will chew up the bottom of the insert and then exit
the top leaving a larger opening than zero clearance. The second one is
really bad and this is that if you use the fence to hold down the insert
you must be sure to put it on the side opposite the blade direction and
there just may not be enough "bite" on this narrower side to keep the
insert clamped in place. I suppose there are other ways to keep the
insert immobile but overall I just cannot see this as practical. Anyone
else care to chime in here?

inserts....
